Scientists Can Now Unboil Eggs To Hopefully Make Cancer Drugs Cheaper

It sounds like research that doesn't have much more of a practical application than making people say "neat", but chemists at UC Irvine have figured out a way to unboil egg whites — turning them from a solid back into a liquid — and the process behind it promises to help lower the production cost of cancer drugs and other expensive medications.

The act of unboiling an egg that spent 20 minutes in hot water is actually just a fun way to show off just how powerful this new process can be. On a more practical level, it means that scientists can use and recycle molecular proteins that have a tendency to "misfold" into tiny shapes and structures when produced that actually make them unusable. In laymen's terms, the proteins scientists produce in a lab often end up like the spongy white material in a hard-boiled egg, when researchers actually need it to be more of a liquid like in a raw egg.

The new process certainly sounds complicated:

To re-create a clear protein known as lysozyme once an egg has been boiled, he and his colleagues add a urea substance that chews away at the whites, liquefying the solid material. That's half the process; at the molecular level, protein bits are still balled up into unusable masses. The scientists then employ a vortex fluid device, a high-powered machine designed by Professor Colin Raston's laboratory at South Australia's Flinders University. Shear stress within thin, microfluidic films is applied to those tiny pieces, forcing them back into untangled, proper form.

But compared to older and more expensive methods that take up to four days to complete, the new process takes just minutes to untangle the proteins. This time-saving process could both simplify and streamline the creation of specific proteins that many cancer drugs rely on, allowing them to simply be recycled from other more common sources. And if pharmaceutical companies are able to produce these drugs faster and cheaper, it hopefully means they would then pass the savings onto cancer patients dependent on those medications.

TPG currently stands as the second largest internet service provider (ISP) in Australia, and is a force to be reckoned with in the telecommunications industry. Its rapid growth is mainly attributed to strategic acquisitions it has made in recent years. One of those acquisitions was iiNet, an ISP that boasted high customer satisfaction and respect in the community.
A year after TPG bought iiNet, the situation looks bleak for the ISP that was once the darling of the telco industry. Most recently, iiNet's Sydney office was shut down, most of its staff made redundant. We spoke to one former iiNet employee to get the insider story on the aftermath of the TPG acquisition. We also spoke with iiNet, to get its side of the story.

Consider the humble light globe. It hides in your ceiling, turning electricity into light, but little do you know how inefficiently it's doing that. Halogen light bulbs aren't great, but traditional incandescents are downright terrible. Ikea says that the average Aussie household could save nearly $150 a year by switching its lighting to LEDs.
